Question

Use the bar graph to find the experimental probability of the event.

A bar graph, titled Spinning a spinner. Horizontal axis shows number spun. Vertical axis shows times spun. The first bar is labeled 1. It ends at 8. The second bar is labeled 2. It ends at 6. The third bar is labeled 3. It ends at 9. The fourth bar is labeled 4. It ends at 11. The fifth bar is labeled 5. It ends at 9. The sixth bar is labeled 6. It ends at 7.

The experimental probability of not spinning a 1 is

Answer 1

Answer: 21/25 or 0.84

Explanation:

8+6+9+11+9+7=50

50-8=42

42/50=21/25=0.84

Answer 2

To find the experimental probability of not spinning a 1, we need to determine the total number of spins and the number of spins that resulted in not landing on 1.

From the bar graph, we can see that the bar labeled "1" ends at 8, indicating that the spinner landed on 1 a total of 8 times.

To find the total number of spins, we sum up the values at the end of each bar:

Total number of spins = 8 + 6 + 9 + 11 + 9 + 7 = 50

The number of spins that did not result in landing on 1 is the sum of the values at the ends of the bars labeled 2, 3, 4, 5, and 6:

Number of spins not landing on 1 = 6 + 9 + 11 + 9 + 7 = 42

Now, we can calculate the experimental probability of not spinning a 1 by dividing the number of spins not landing on 1 by the total number of spins:

Experimental probability of not spinning a 1 = Number of spins not landing on 1 / Total number of spins

Experimental probability of not spinning a 1 = 42 / 50

Experimental probability of not spinning a 1 = 0.84 or 84%

Therefore, the experimental probability of not spinning a 1 is 84%.
